Education Webinar

Steel Deck Diaphragm Design

May 9, 2023 | Tue 12:00 America/Chicago

Duration: 1.5 Hours

CE Credits: 1.5

$300

This presentation describes the seismic design of concrete-filled steel deck diaphragms based on the latest research. Design equations in the latest (and in some cases upcoming) code editions along with supporting research will be presented for the two basic limit states of diagonal tension cracking and shear transfer failure. An example will be provided to demonstrate the design of a concrete-filled steel deck diaphragm for these limit states using demands calculated with the alternative diaphragm design provisions in ASCE 7. Calculation of diaphragm deflections and design of shear transfer along collectors will also be discussed. The presentation will conclude with a description of how buildings will perform during earthquakes if designed using these approaches.

  • Course will award 1.5 hours of continuing education
  • This course is Diamond Review approved in 49 states. New York does not accept hours from recordings.

Please note: This webinar is part of the Seismic Design Series and is not included in the NCSEA Webinar Subscription.

Speaker:

Matt Eatherton, Ph.D., S.E., is a Professor in the Department of Civil and Environmental Engineering at Virginia Tech. He conducts research on diaphragms and floor systems in steel buildings, as well as seismic design of steel structures. He is a part of the Steel Diaphragm Innovation Initiative (SDII) www.steeli.orgthat generated a number of updates to steel deck diaphragm design provisions in recent years. He has seven years of practicing structural engineer experience and sixteen years of academic experience. He has been awarded several honors including the AISC Milek Faculty Fellowship, NSF Career award, AISC Early Faculty Award, ASCE Moissef Paper Award, and the Curry Faculty Fellowship at Virginia Tech.

NCSEA Webinars and Digital Events Cancellation and Refund PoliciesWebinar CancellationBy NCSEA: If a webinar is canceled by NCSEA, all registered attendees will be notified via email. NCSEA will issue a full refund if the event cannot be rescheduled. If the event is rescheduled and a registrant can not attend on the rescheduled date, NCSEA will offer a credit in the amount of the purchase price.By Registrant/Attendee: Cancellations must be made at least 24 hours in advance of the webinar (or the first webinar in the case of a series or bundle) and in writing via email ( ncsea@ncsea.com) with the subject line “NCSEA Webinar Cancellation” and include the following in the body of the email: Title of Webinar, Order/Invoice Number, Name of Registrant, and Reason for Cancellation. No telephone refund requests will be accepted.

If the request has been approved, NCSEA can do one of the following:

  • Refund the amount back to the original order payment method (a $25 cancellation processing fee will be assessed)
  • Issue a full credit on the purchaser’s account that can be used towards a future webinar/event.

If you are unable to attend the webinar and the cancellation deadline has passed, a recording will be available (in most cases) in the Education Portal after the webinar has concluded.
Refunds are not granted due to attendee technology issues. It is your responsibility as the webinar attendee to test your computer setup prior to the start of the webinar.
